We present a computational analysis of the long-range interactions of solitary waves in higher-order field theories. Our vehicle of choice is the $\varphi^8$ field theory, although we explore similar issues in example $\varphi^{10}$ and $\varphi^{12}$ models. In particular, we discuss the fundamental differences between the latter higher-order models and the standard $\varphi^4$ model. Upon establishing the power-law asymptotics of the model's solutions' approach towards one of the steady…

A $$\phi ^6$$ soliton with a long-range tail
We propose an analytically solvable sextic potential model with non-trivial soliton solutions connecting the trivial vacua. The model does not respect parity symmetry, and like $$\phi ^4$$ theory has
Kink-Antikink Collisions in the Periodic $\varphi^{4}$ Model
We borrow the form of potential of the well-known kink-bearing $\varphi^4$ system in the range between its two vacua and paste it repeatedly into the other ranges to introduce the periodic
Kink–antikink interaction forces and bound states in a biharmonic ϕ 4 model
We consider the interaction of solitons in a biharmonic, beam model analogue of the well-studied $\phi^4$ Klein-Gordon theory. Specifically, we calculate the force between a well separated kink and
Four Decades of Kink Interactions in Nonlinear Klein-Gordon Models: A Crucial Typo, Recent Developments and the Challenges Ahead
The study of kink interactions in nonlinear Klein-Gordon models in $1+1$-dimensions has a time-honored history. Until a few years ago, it was arguably considered a fairly mature field whose main
Kink–antikink interaction forces and bound states in a ϕ 4 model with quadratic and quartic dispersion
We consider the interaction of solitary waves in a model involving the well-known ϕ 4 Klein–Gordon theory, but now bearing both Laplacian and biharmonic terms with different prefactors. As a result
Semi-compactness and multiple oscillating pulses in kink scattering
In this work we consider models of asymmetric kinks, where the behavior of the solution in one side is different from the other side. Also, the models depend of an integer $n$ and, with the increase

Intersoliton forces in weak-coupling quantum field theories
We offer a procedure for evaluating the forces exerted by solitons of weak-coupling field theories on one another. We illustrate the procedure for the kink and the antikink of the two-dimensional
Kink-Antikink Collisions in the φ4 Equation: The n-Bounce Resonance and the Separatrix Map
A detailed mathematical explanation of a phenomenon known as the two-bounce resonance observed in collisions between kink and antikink traveling waves of the $\phi^4$ equations of mathematical physics, including the origin of several mathematical assumptions needed by previous researchers are provided.
Kink-Antikink Scattering in \phi^4 and \phi^6 Models
For kink-antikink scattering within the \phi^4 non--linear field theory in one space and one time dimension resonance type configurations emerge when the relative velocity between kink and antikink
Kink dynamics in a parametric ϕ6 system: a model with controllably many internal modes
A bstractWe explore a variant of the ϕ6 model originally proposed in Phys. Rev.D 12 (1975) 1606 as a prototypical, so-called, “bag” model in which domain walls play the role of quarks within hadrons.
Kink interactions in the (1+1)-dimensional $\phi^6$ model
We study kink scattering processes in the ( 1 + 1 ) -dimensional φ 6 model in the framework of the collective coordinate approximation. We find critical values of the initial velocities of the
Higher-order field theories: $φ^6$, $φ^8$ and beyond
The φ model has been the “workhorse” of the classical Ginzburg– Landau phenomenological theory of phase transitions and, furthermore, the foundation for a large amount of the now-classical
Kink-Antikink Collisions in the Two-Dimensional φ4 Model
Inelastic kink-antikink collisions are investigated in the two-dimensional ¢' model. It is shown that a bound state of the kink and antikink is formed when the colliding velocity V is less than a
Scattering of the double sine-Gordon kinks
We study the scattering of kink and antikink of the double sine-Gordon model. There is a critical value of the initial velocity $$v_{{\mathrm {cr}}}$$vcr of the colliding kinks, which separates
Fractal structure in the scalar λ ( φ 2 − 1 ) 2 theory
Head-on collisions of kink and antikink solitons are investigated numerically in the classical one-dimensional λ(Φ 2 -1) 2 model. It is shown that whether a kink-antikink interaction settles to a
